There could be multiple reasons why the FTP connection from Python to mainframe machine is not functioning properly in a Docker container. Below are some of the possible reasons:
Network connectivity issues: Docker containers operate in a virtual network environment which may not be properly configured to access external networks, including the mainframe network.
Firewall restrictions: The firewall settings may be blocking the FTP connection from Python to the mainframe machine within the Docker container.
Operating system compatibility issues: The Docker container may not be running the same operating system as the mainframe machine, which may result in compatibility issues between the FTP client and server.
Library dependencies: The required libraries for Python FTP may not be installed or properly configured in the Docker container.
To resolve this issue, you can try the following:
Verify that the Docker container is properly configured to access the mainframe network, and that any required firewall ports are opened.
Ensure that the FTP client used within the Python code is compatible with the mainframe machine's FTP server.
Verify that all necessary libraries are installed and properly configured within the Docker container.
If necessary, consider using a different protocol for file transfer (such as SFTP) that may be better suited for the Docker environment.
